DM_WF_MDV4 - stodev-com-br/tasmota GitHub Wiki
This Device is based on a Tuya Wi-Fi Module. Refer to "MCU Based Tuya Dimmers and Switches" for details.

This is a 240V Leading Edge Dimmer with a TYWE3S controller and an STM8 MCU
Flashing:
The NRST pin of the STM8 needs to be grounded upon boot to disable it, this is brought out to a header pin, along with ground and VCC from the TYWE3S. Confirm by checking continuity with a multimeter
IO0 from the TYWE3s also needs to be grounded upon boot, otherwise it's normal tasmota flashing procedure.
Header pins from left to right *VCC *Unknown *Ground *STM8 NRST



Config:
As per main TuyaMCU page using
| GPIO | Component |
|---|---|
| 01 | Tuya Rx (108) |
| 03 | Tuya Tx (107) |
